Summary
OpenBMB ChatDev - Unauthenticated Path Traversal in Upload Handler Allows Arbitrary File Write and Delete
Details

OpenBMB ChatDev through 2.2.0, fixed in commit 4fd4da6, contains a path traversal vulnerability that allows unauthenticated remote attackers to write or delete arbitrary files by supplying a malicious multipart filename in the file upload endpoint. Attackers can send a crafted filename containing path traversal sequences or an absolute path to the POST uploads session endpoint, which constructs the destination path without sanitization in saveuploadfile, causing file write and cleanup operations to target attacker-chosen paths on the server filesystem.
